2018 3500 EXT Camper Conversion in CT (TX for now due to Covid)
Way more than needed, I used a 3000 VA Victron with a 600AH LiFePO4 battery bank. The AC only draws 40-50 amps , 500-600watts. A 1500-2000 watt inverter should be sufficient for my unit as long as it has the surge capacity to start it. I got the inverter for the 120 amp charging capacity and other features
more than the size of the inverter.
